Questions & Step-by-Step Solutions
A wave on a string has a frequency of 60 Hz and a wavelength of 0.5 m. What is the speed of the wave? (2021)
Step 1: Identify the frequency of the wave, which is given as 60 Hz.
Step 2: Identify the wavelength of the wave, which is given as 0.5 m.
Step 3: Use the formula for wave speed, which is Speed (v) = Frequency (f) × Wavelength (λ).
Step 4: Substitute the values into the formula: v = 60 Hz × 0.5 m.
Step 5: Calculate the result: 60 × 0.5 = 30.
Step 6: State the speed of the wave: The speed is 30 m/s.
Wave Speed Calculation – The speed of a wave can be calculated using the formula v = f × λ, where v is the speed, f is the frequency, and λ is the wavelength.
